jQuery 中的each()方法与 JavaScript 的for循环类似。each()方法可以遍历数组和对象。 同时,要遍历 JavaScript 中的对象,我们需要使用for in循环。让我们看一个 JavaScript 中的for循环示例: <!DOCTYPE html>JavaScript For Loop<pid="DemoPara">constDemo_Array=["Delftstack1","Delftstack2","Delftstack3","D...

在使用jQuery在for循环中存储数组时,可以使用jQuery的data()方法来实现。data()方法允许我们在DOM元素上存储任意类型的数据。 下面是一个示例代码,演示如何使用jQuery在for循环中存储数组: 代码语言:html 复制 <!DOCTYPE html> $(document).ready(function() { var myArray = [1, 2, 3, 4, 5];...
// for-in loop without checking hasOwnProperty() for(variinman) { console.log(i,":", man[i]); } /* 控制台显示结果 hands : 2 legs : 2 heads : 1 clone: function() */ 另外一种使用hasOwnProperty()的形式是取消Object.prototype上的方法。像这样: ...
